Direction: Two statements are followed by two Conclusions I and II. You have to consider the statements to be true, even if they seem to be at variance from commonly known facts. You are to decide which of the given conclusions can definitely be drawn from the given statements and indicate your answer accordingly.

Statements:

1. The demand for clothes from non-Indian brands is increasing more rapidly than indigenous clothing brands.

2. The above mentioned non-Indian brands are looking for a way to reduce the cost of their products.

Conclusions:

I. The non-Indian clothing brands should manufacture their products in India.

II. A new product from indigenous clothing brands would reduce the current high demand for non-Indian clothing products.
Detailed Solution for IBPS RRB PO (Scale 1) Mains Mock Test - 4 - Question 16
The statements clearly state that non-Indian brands are trying to find a way to meet the demand of the market while keeping the cost low. Therefore, installing a manufacturing plant in India would increase the supply as well as reduce the retail price of the clothing products. The second conclusion does not completely comply with the above statements as the demand for products from indigenous brands is not as high as that of non-Indian brands. It may be an assumption but cannot be qualified as a conclusion of the above statements. So, only conclusion I follows.

Hence, the correct option is (A).

Direction: The question below consists of a question and three statements numbered I, II and III given below it. You have to decide whether the data provided in the statements are sufficient to answer the question.

Q. What is the code for ‘right’ in the coded language?

I. ‘op pq te’ means ‘she is right’ and ‘pq qr sm’ means ‘he is sincere’.

II. ‘nm pu sf’ means ‘they are dancing’ and ‘pt sn pq’ means ‘sky is clear’.

III. ‘op fr pq’ means ‘she is dancing’ and ‘te nm ln’ means ‘they answered right’.
Detailed Solution for IBPS RRB PO (Scale 1) Mains Mock Test - 4 - Question 17
As per the data in the question,

I. ‘op pq te’ means ‘she is right’ and ‘pq qr sm’ means ‘he is sincere’.

pq = is,

Thus, Statement I alone is not sufficient to answer the question.

II. ‘nm pu sf’ means ‘they are dancing’ and ‘pt sn pq’ means ‘sky is clear’.

Thus, Statement II alone is not sufficient to answer the question.

III. ‘op fr pq’ means ‘she is dancing’ and ‘te nm ln’ means ‘they answered right’.

Thus, Statement III alone is not sufficient to answer the question.

Now, let us check with Statement I and II,

I. ‘op pq te’ means ‘she is right’ and ‘pq qr sm’ means ‘he is sincere’.

II. ‘nm pu sf’ means ‘they are dancing’ and ‘pt sn pq’ means ‘sky is clear’.

pq = is

Thus, Statement I and II are not sufficient to answer the question.

Now, let us check with Statement II and III,

II. ‘nm pu sf’ means ‘they are dancing’ and ‘pt sn pq’ means ‘sky is clear’.

III. ‘op fr pq’ means ‘she is dancing’ and ‘te nm ln’ means ‘they answered right’.

nm = they, pq = is

Thus, Statement II and III are not sufficient to answer the question.

Now, let us check with Statement I and III,

I. ‘op pq te’ means ‘she is right’ and ‘pq qr sm’ means ‘he is sincere’.

III. ‘op fr pq’ means ‘she is dancing’ and ‘te nm ln’ means ‘they answered right’.

pq = is , op = she, te = right

Thus, Statement I and III are sufficient to answer the question.

So, data of the Statement I and III are sufficient to answer the question.

Hence, the correct option is (B).

Step 2: 162063 243524 21854 22720 54335 6640

Step 5 is the last step of rearrangement. As per the rules followed in the above steps, find out in each of the following questions the appropriate steps for the given input.

Input for the given Question,

Input: 576218 415893 642739 717340 931621 842163.

What is the Addition of 3rd element from left end in step 2 and 3rd element from right end in step 1?
Detailed Solution for IBPS RRB PO (Scale 1) Mains Mock Test - 4 - Question 19
The Digits are arranged in such a way that,

In step 1 = if digit starts with odd number then it will be reverse and if it starts with even number then it will be reverse in pair of two.

Suppose in the given input it is 962437 starts with odd number i.e., 9. So in step 1 it will be reversed and we get 734269. In case of 465783 it will be 647538.

In step 2 = At first, the even digit numbers are arranged in descending order then the odd digit numbers are arranged in their respective order. After that multiplication of two-two digits of those are taken.

Ex – In step 1, the even digits numbers are = 825497 and 647538 now arranged them in descending order we get 825497 and 647538 so the multiplication form of 825497 is 8 × 2 = 16 5 × 4 = 20 and 9 × 7 = 63 i.e., 162063.

(This is the 1st number of step 2).

We get 162063 and 243524 from step 1(825497 647538 respectively).

Then the multiplications of odd numbers are arranged according their positional value.

21854 comes form 734269, 22720 from 129354, 54335 from 54335 and 6640 from 6640.

In step 3 = Difference of Addition of odd and even digits within the number.

Ex – 162063, 6 + 6 + 2 = 14, 3 + 1 = 4, 14 – 4 = 10.

In step 4 = Square of 1, 2, 3….so on and then add that Square in the numbers in Ascending order means Square of 1 is added in 1 and Square of 2 added in 4 and so on.

In step 5 = Addition of two numbers, than again add the digits of the number obtained.

Ex – 2 + 8 (1st and 2nd number of step 4) = 10 then 1 + 0 = 1 (1st number of step 5).

And 8 + 17 (2nd and 3rd number of step 4) = 25 = 2 + 5 = 7 (2nd number of step 5).

So, the solution of given input will be like this-

Input: 576218 415893 642739 717340 931621 842163

Step 1: 812675 148539 467293 43717 126139 481236

Step 2: 81235 32218 241427 1277 44027 2627

Step 5 is the last step of rearrangement.

3rd element from left end in step 2 is 241427 and 3rd element from right end in Step 1 is 43717.

241427 + 43717 = 285144.

Hence, the correct option is (B).

Direction: In a certain number system there are only two notations to represent numbers: # and %.

0 is represented by % and 1 by #. The subsequent numbers are represented in the following manner:

2 is represented as #%,

3 is represented as ##,

4 is represented as #%%,

5 is represented as #%# and so on.

Based on this coded language, answer the following questions.

What is the resultant of the following expression?

###%# ÷ #% × ##%% + ##% × #%#
Detailed Solution for IBPS RRB PO (Scale 1) Mains Mock Test - 4 - Question 23
According to the given information,

So, this entire code language is based on only 2 symbols % and #, i.e. 0 and 1.

Logic:

On observation, we notice that starting from the rightmost digit, each digit is multiplied with corresponding power of 2, starting with 20, and then all these terms are added to obtain the number in the decimal system.

[The rightmost term is multiplied with 20, the second term from right is multiplied with 21, the third term from right is multiplied with 22 and so on..]

2 → 10 ⇒ (0 × 20) + (1 × 21) = (0 × 1) + (1 × 2) = 0 + 2 = 2

3 → 11 ⇒ (1 × 20) + (1 × 21) = (1 × 1) + (1 × 2) = 1 + 2 = 3

4 → 100 ⇒ (0 × 20) + (0 × 21) + (1 × 22) = (0 × 1) + (0 × 2) + (1 × 4) = 0 + 0 + 4 = 4

5 → 101 ⇒ (1 × 20) + (0 × 21) + (1 × 22) = (1 × 1) + (0 × 2) + (1 × 4) = 1 + 0 + 4 = 5 and so on.

Based on this logic,

‘###%#’ ↔ 11101

11101 ⇒ (1 × 20) + (0 × 21) + (1 × 22) + (1 × 23) + (1 × 24)

= (1 × 1) + (0 × 2) + (1 × 4) + (1 × 8) + (1 + 16)

= 1 + 0 + 4 + 8 + 16 = 29

‘#%’ ↔ 10

10⇒ (0 × 20) + (1 × 21)

= (0 × 1) + (1 × 2)

= 0 + 2 = 2

'##%%' ↔ 1100

1100 ⇒ (0 × 20) + (0 × 21) + (1 × 22) + (1 × 23)

= 0 + 0 + 4 + 8 = 12

'##%' ↔ 110

110 ⇒ (0 × 20) + (1 × 21) + (1 × 22)

= 0 + 2 + 4 = 6

'#%#' ↔ 101

101 ⇒ (1 × 20) + (0 × 21) + (1 × 22)

= 1 + 0 + 2 = 5

The resultant of the expression is: 29 ÷ 2 × 12 + 6 × 5 = 204

Now, we need to convert 204 into the given code language.

204 = 128 + 64 + 8 + 4

∴ 204 = (0 × 20) + (0 × 21) + (1 × 22) + (1 × 23) + (0 × 24) + (0 × 25) + (1 × 26) + (1 × 27)

∴ 204 ⇒ 11001100

Converting 0s and 1s to %s and #s respectively, we get

204 = ##%%##%%

So, the resultant of the expression "###%# ÷ #% × ##%% + ##% × #%#" is ##%%##%%.

Hence, the correct option is (C).

Based on this logic,

‘###%#’ ↔ 11101

11101 ⇒ (1 × 20) + (0 × 21) + (1 × 22) + (1 × 23) + (1 × 24)

= (1 × 1) + (0 × 2) + (1 × 4) + (1 × 8) + (1 + 16)

= 1 + 0 + 4 + 8 + 16 = 29

‘#%’ ↔ 10

10⇒ (0 × 20) + (1 × 21)

= (0 × 1) + (1 × 2)

= 0 + 2 = 2

'##%%' ↔ 1100

1100 ⇒ (0 × 20) + (0 × 21) + (1 × 22) + (1 × 23)

= 0 + 0 + 4 + 8 = 12

'##%' ↔ 110

110 ⇒ (0 × 20) + (1 × 21) + (1 × 22)

= 0 + 2 + 4 = 6

'#%#' ↔ 101

101 ⇒ (1 × 20) + (0 × 21) + (1 × 22)

= 1 + 0 + 2 = 5

The resultant of the expression is: 29 ÷ 2 × 12 + 6 × 5 = 204

Now, we need to convert 204 into the given code language.

204 = 128 + 64 + 8 + 4

∴ 204 = (0 × 20) + (0 × 21) + (1 × 22) + (1 × 23) + (0 × 24) + (0 × 25) + (1 × 26) + (1 × 27)

∴ 204 ⇒ 11001100

Converting 0s and 1s to %s and #s respectively, we get

729 = #%##%##%%#

So, the square of "##%##" is "#%##%##%%#".

Hence, the correct option is (B).

Based on this logic,

‘###%#’ ↔ 11101

11101 ⇒ (1 × 20) + (0 × 21) + (1 × 22) + (1 × 23) + (1 × 24)

= (1 × 1) + (0 × 2) + (1 × 4) + (1 × 8) + (1 + 16)

= 1 + 0 + 4 + 8 + 16 = 29

‘#%’ ↔ 10

10⇒ (0 × 20) + (1 × 21)

= (0 × 1) + (1 × 2)

= 0 + 2 = 2

'##%%' ↔ 1100

1100 ⇒ (0 × 20) + (0 × 21) + (1 × 22) + (1 × 23)

= 0 + 0 + 4 + 8 = 12

'##%' ↔ 110

110 ⇒ (0 × 20) + (1 × 21) + (1 × 22)

= 0 + 2 + 4 = 6

'#%#' ↔ 101

101 ⇒ (1 × 20) + (0 × 21) + (1 × 22)

= 1 + 0 + 2 = 5

The resultant of the expression is: 29 ÷ 2 × 12 + 6 × 5 = 204

Now, we need to convert 204 into the given code language.

204 = 128 + 64 + 8 + 4

∴ 204 = (0 × 20) + (0 × 21) + (1 × 22) + (1 × 23) + (0 × 24) + (0 × 25) + (1 × 26) + (1 × 27)

∴ 204 ⇒ 11001100

Converting 0s and 1s to %s and #s respectively, we get

298 = #%%#%#%#%

So, the resultant of the expression "39 × 5 + 114 × 2 − 125" will be coded as ‘#%%#%#%#%'.

Hence, the correct option is (A).

What is the difference between 2nd letter from right end in Step 5 and 2nd letter from left end in step 3?
Detailed Solution for IBPS RRB PO (Scale 1) Mains Mock Test - 4 - Question 26

The Digits are arranged in such a way that,

In step 1 = if digit starts with odd number then it will be reverse and if it starts with even number then it will be reverse in pair of two.

Suppose in the given input it is 962437 starts with odd number i.e., 9. So in step 1 it will be reversed and we get 734269. In case of 465783 it will be 647538.

In step 2 = At first, the even digit numbers are arranged in descending order then the odd digit numbers are arranged in their respective order. After that multiplication of two-two digits of those are taken.

Ex – In step 1, the even digits numbers are = 825497 and 647538 now arranged them in descending order we get 825497 and 647538 so the multiplication form of 825497 is 8 × 2 = 16 5 × 4 = 20 and 9 × 7 = 63 i.e., 162063.

(This is the 1st number of step 2).

We get 162063 and 243524 from step 1(825497 647538 respectively).

Then the multiplications of odd numbers are arranged according their positional value.

21854 comes form 734269, 22720 from 129354, 54335 from 54335 and 6640 from 6640.

In step 3 = Difference of Addition of odd and even digits within the number.

Ex – 162063, 6 + 6 + 2 = 14, 3 + 1 = 4, 14 – 4 = 10.

In step 4 = Square of 1, 2, 3….so on and then add that Square in the numbers in Ascending order means Square of 1 is added in 1 and Square of 2 added in 4 and so on.

In step 5 = Addition of two numbers, than again add the digits of the number obtained.

Ex – 2 + 8 (1st and 2nd number of step 4) = 10 then 1 + 0 = 1 (1st number of step 5).

And 8 + 17 (2nd and 3rd number of step 4) = 25 = 2 + 5 = 7 (2nd number of step 5).

So, the solution of given input will be like this-

Input: 576218 415893 642739 717340 931621 842163

Step 1: 812675 148539 467293 43717 126139 481236

Step 2: 81235 32218 241427 1277 44027 2627

Step 5 is the last step of rearrangement.

2nd letter from right end in Step 5 is 8 and 2nd letter from left end in Step 3 is 8

8 – 8 = 0

Hence, the correct option is (E).
